GOUNTERBALANGING Ann ADJUSTABLE sasn mi wmnows.

To (all whom it may concern:

Be it known that I, IVILLIAM IIJ'PEADEN, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and'useful Improvements in Counterbalancing and Adjustable Sashes for Windows, ofwhlch the following is a specification reference being had to the, accompanying drawings- It is the purpose of the to provide means on opposite sides of a winof counterbalanclng means and lower sashes of a wlndow casement, in.

dow casement or frame, for notonly counter- I balancing the upper and lower sashes thereof, but providing means for raising one or the other of the sashes, when both sashes are in lowered positions. Y

. Another purpose consists in the provision for'the upper combination with adjustable suspension means for supporting the counterbalancing connections between the upper and lower ent illustrated and set tion, and

sashes, so that it is possible to holdone or V the Iother of said sashes in a lowered posiraise; the other sash by operating,

this suspension means.

. In the application of the present invention,

itis the aim to mount the counterbalancing means and the suspension means,.in the parting strip between the two sashes, at the upperfpart of the easement, whereby access to the suspension means may be easily had from for the purpose of manipulating the counterbalancing connections between the sashes. I i

It is to. be noted that the parting strip acts as such, and also constitutes a carrier for the counterbalancingconnections and the suspension operation means The counterbalancing connections and the suspension means maybe mounted in the bottom of a channel member, the metal wall of which is bent to provide overlying flanges,

which are so spaced as to constitute a parti-n strip.

1 IVhile the design and construction at pres- V forth is 'deemedpreferable, it is obvious thatas a result of areduction of the invention to a more. practical form for commercial purposes, theinvention may be susceptible of changes, and the right .to these changes is claimed, provided they are comprehended. within the scope ofwhat is. claimed.

'he invention comprises further features present invention sash may be made...

This strip is inset in the wall ofthe casement as shown at 2, and'projects sufficiently between thesashes, to act as a parting strip, for guiding the upper and lower sashes. A parting strip of" this character-is mounted at the upper portion of each side of the window casement, extending substan.-' tially half the height of the casement. In

other words the hollow parting strip, asshown especially in Figure 5 extends from the top of the window casement or frame to the top rail of the lower sash, and does not extend to the baseof the casement or window frame. shorten this hollow parting strip midway of the casement or window frame, inorder that connections of the chain-withthe upper It is necessary to terminate or The upper part oithe I parting strip has a P ojectin pelt?

' Mounted to move inthe channel of each parting strip is a movable hanger 9 carrying pulleys 10 and 11,. A suspension guiding chain or cable, cord or the like 12 is connected to the hanger 9 asat-13, and extendsthrough the channel of the parting strip and over the revoluble member 7,

Also in Figure 7, where the suspension and counterbalancing means are mounted in the casing, the sheet metal of the casing is bent outwardly to provide overlying flanges, which form a parting strip between the sashes of the-"window. It will be noted that these flanges 22 are yieldable, preventing the upper and lower sashes from 7 binding. 7
